What's the differences between animism, polytheism and monotheism?

Animism is the belief that everything has a soul or a spirit. Polytheism is the belief of more than one God. Monotheism is the belief in one God or the oneness of God. ( I hope this helped )

Monotheism= one god, Polytheism= more than one god, Animism= nature
